The animation is decent, but why does Yoda look so angry at the end?

Anyway the lighting and rendering looked very fake, but I thought Yoda at the funeral was pretty damn impressive, looked pretty real. Too bad it looks like typical video game integration in most shots, although it is also kind of rewarding to get facial animation which is half decent. The original version was awful too, so I'm not sure if anyone should be complaining or not. I guess we should be complaining that Yoda hasn't looked right since 1983 no matter the film.
